Rio's two nights of famously extravagant Carnival parades began late on February 18in a burst of fireworks and to the cheers of festival goers who have been partying on the streets for days. The processions, featuring near-naked dancing queens, spectacularly imaginative floats and thousands of extras, were being held before a stadium crowd of 70,000 and an international broadcast audience.
